What USDA hardiness zones is Endless Summer® The Original Bigleaf Hydrangea rated for?

  • Endless Summer® The Original Bigleaf Hydrangea is hardy in USDA zones 4-9. This cold-hardy selection can withstand harsh winters while still producing blooms on both old and new wood. Plant in spring after your last frost date for best establishment.

  • The Original Endless Summer® Hydrangea reaches 3-5 feet tall and wide at maturity. This compact size makes it perfect for foundation plantings or mixed borders where you want substantial flower power without overwhelming nearby plants. Shop at Nature Hills for this reliable rebloomer.

What are the planting requirements for Endless Summer® The Original Bigleaf Hydrangea, including sun exposure and soil type?

  • Endless Summer® The Original thrives in partial shade to morning sun with well-draining soil. Plant in alkaline soil for pink blooms or acidic soil for blue flowers. Ensure consistent moisture but avoid waterlogged conditions for best flowering performance.

How do I care for Endless Summer® The Original Bigleaf Hydrangea, especially watering needs?

  • Water consistently to keep soil evenly moist but not waterlogged, as hydrangeas prefer steady moisture levels. These hardy shrubs benefit from deep watering 1-2 times weekly rather than frequent shallow watering. Apply mulch around the base to retain moisture and water early morning to reduce leaf diseases.

When and how should I prune Endless Summer® The Original Bigleaf Hydrangea, particularly in snowy or cold areas?

  • Prune Endless Summer® hydrangeas in late winter or early spring, removing only dead or damaged wood since they bloom on both old and new growth. In cold areas, leave stems standing through winter for protection and cold hardiness. Light pruning maintains the best flower production on this reblooming variety available at naturehills.com.
